Description

管件连接装置 技术领域
本发明涉及管件连接技术领域，具体涉及一种管件连接装置。
背景技术
管件在安装的过程中，为了保证管件连接装置之间的密封性，常常需要使用卡钳对管材进行压接。由于卡钳的种类繁多，传统的管件连接装置无法与全部的卡钳实现通用的匹配，而且不同卡钳的卡齿高度不一致，导致压接管材的过程中，压痕数量以及压痕处的压缩量不同，无法有效的保证管件连接装置与管材之间的密封性。
发明内容
基于此，有必要提供一种管件连接装置，能够与多种卡钳配套使用，保证管件连接装置与管材之间的密封性。
其技术方案如下：
一种管件连接装置，包括：管件本体，所述管件本体包括相互连接的芯体和连接体，所述连接体上设有第一配合部；定位套，所述定位套套设于所述芯体上，且所述定位套的一端设有与所述第一配合部相匹配的第二配合部，使所述定位套与所述芯体间隔设置形成供管材安装的安装腔，所述定位套的外壁上间隔设有至少两条定位筋，相邻的两条定位筋与定位套配合形成与卡齿配合的夹槽。
上述管件连接装置安装使用时，将定位套沿管件本体的长度方向套设于芯体上，直至第二配合部与第一配合部实现配合，从而实现定位套相对管件本体的安装固定，定位套与芯体之间留有间隙，该间隙形成了供管材安装的安装腔，将管材插入该安装腔内直至管材与安装腔的底壁相抵接，利用卡钳对定位套进行夹持使定位套和管材压缩变形从而实现密封，当卡钳的卡齿高度较低时，例如H型卡钳、VP型卡钳等，将卡齿放入夹槽内，定位筋与卡钳的内壁相抵接， 卡钳咬合时，卡齿的咬合力使得夹槽的底壁进行压缩，同时，卡钳的内壁的咬合力也使得定位筋进行压缩，从而使得管材多处变形压缩，保证了管件连接装置与管材之间密封的可靠性；当卡钳的卡齿高度较高时，例如TH型卡钳、F型卡钳、U型卡钳等，将卡齿放入夹槽内，定位筋与卡钳的内壁之间留有间隙，卡钳咬合时，卡齿的咬合力使得夹槽的底壁进行压缩，同时，卡钳的咬合也消除了定位筋与卡钳的内壁之间的间隙，卡钳在进一步咬合时，卡钳的内壁的咬合力也使得定位筋进行压缩，同样使得管材多处变形压缩，保证了密封的可靠性，并且，经过卡钳的进一步咬合，夹槽底壁的压缩量也进一步加强，增强了密封性。

如图1、图2及图4所示，本发明一个实施例的一种管件连接装置，包括：管件本体100，管件本体100包括相互连接的芯体110和连接体120，连接体120上设有第一配合部121；定位套300，定位套300套设于芯体110上，且定位套300的一端设有与第一配合部121相匹配的第二配合部330，使定位套300与芯体110间隔设置形成供管材600安装的安装腔400，定位套300的外壁上间隔设有至少两条定位筋310，相邻的两条定位筋310与定位套300配合形成与卡齿710配合的夹槽320。
如图5至图9所示，上述实施例的管件连接装置安装使用时，将定位套300沿管件本体100的长度方向套设于芯体110上，直至第二配合部330与第一配合部121实现配合，从而实现定位套300相对管件本体100的安装固定，定位套300与芯体110之间留有间隙，该间隙形成了供管材600安装的安装腔400，将管材600插入该安装腔400内直至管材600与安装腔400的底壁相抵接，利用卡钳700对定位套300进行夹持使定位套300和管材600压缩变形从而实现 密封，当卡钳700的卡齿710高度较低时，例如H型卡钳、VP型卡钳等，将卡齿710放入夹槽320内，定位筋310与卡钳700的内壁相抵接，卡钳700咬合时，卡齿710的咬合力使得夹槽320的底壁进行压缩，同时，卡钳700的内壁的咬合力也使得定位筋310进行压缩，从而使得管材600多处变形压缩，保证了管件连接装置与管材600之间密封的可靠性；当卡钳700的卡齿710高度较高时，例如TH型卡钳、F型卡钳、U型卡钳等，将卡齿710放入夹槽320内，定位筋310与卡钳700的内壁之间留有间隙，卡钳700咬合时，卡齿710的咬合力使得夹槽320的底壁进行压缩，同时，卡钳700的咬合也消除了定位筋310与卡钳700的内壁之间的间隙，卡钳700在进一步咬合时，卡钳700的内壁的咬合力也使得定位筋310进行压缩，同样使得管材600多处变形压缩，保证了密封的可靠性，并且，经过卡钳700的进一步咬合，夹槽320底壁的压缩量也进一步加强，增强了密封性。
需要进行说明的是，第一配合部121与第二配合部330之间的配合可以是通过凸块与凹槽相配合实现，也可以是通过卡钩与卡钩之间的配合实现，只需满足第一配合部121与第二配合部330的配合能够使得定位套的300安装固定即可。当定位筋310的为两条时，两条定位筋310相对间隔设置，利用卡钳700进行压紧时，将卡齿710放入夹槽320内，卡钳700夹紧后，在夹槽320内及两条定位筋310处形成至少三处压痕，加强了密封性；当定位筋310的为三条时，相邻的两条定位筋310相对间隔设置，利用卡钳700进行压紧时，将卡齿710放入夹槽320内，卡钳700夹紧后，在夹槽320内及三条定位筋310处形成至少四处压痕，进一步加强了密封性。
如图1及图4所示，在上述实施例的基础上，夹槽320的内壁设有用于对卡齿710进行定位的定位部321。通过在夹槽320的内壁设置定位部321，使得卡钳700的卡齿710能够快速的与定位套300实现定位配合，为后续的咬合做好定位准备。定位部321可以是开设在夹槽320底壁上的能够与卡齿710配合的凹槽，也可以是设置在夹槽320侧壁上的能够与卡齿710的侧壁相匹配的斜面，只需满足能够快速、方便的使得卡齿710进行定位即可。
如图1及图5至11所示，在上述任一实施例的基础上，管件连接装置还包 括挡圈，挡圈套设于连接体120上，挡圈用于使定位套300相对芯体110固定，定位套300、挡圈及芯体110配合形成安装腔400。在进行管件连接装置的组装使用时，将挡圈沿管件本体100的长度方向套入，直至挡圈套设于连接体120上，利用挡圈与定位套300的配合从而实现定位套300相对管件本体100的安装固定，定位套300、挡圈及芯体110配合形成供管材600插入的安装腔400，管材600插入至与挡圈相抵接即可。
进一步地，挡圈包括挡圈本体200，挡圈本体200上设有通孔，通孔的内壁设有朝向连接体120设置的第三配合部210，第三配合部210与第一配合部121配合。挡圈本体200安装时，芯体110和连接体120分别穿过通孔，直至第三配合部210与连接体120上的第一配合部121实现配合，从而实现挡圈本体200的安装固定。第三配合部210与第一配合部121之间的配合可以是通过凸块与凹槽相配合实现，也可以是通过卡钩与卡钩之间的配合实现，只需满足第三配合部210与第一配合部121的配合能够使得挡圈本体200安装固定即可。
更进一步地，挡圈本体200上还设有凸缘230，凸缘230与第三配合部210相对间隔设置，凸缘230朝向管材600插入方向的反方向延伸，凸缘230上设有朝向连接体120设置的第一凸部，第一凸部、凸缘230及挡圈本体200配合形成与第二配合部330卡接的第四配合部220。定位套300安装时，将定位套300套设于芯体110，直至第二配合部330与第四配合部220实现配合，从而实现定位套300的安装固定。第二配合部330与第四配合部220之间的配合可以是通过凸块与凹槽相配合实现，也可以是通过卡钩与卡钩之间的配合实现，只需满足第二配合部330与第四配合部220的配合能够使得定位套300安装固定即可。
如图2及图11所示，在上述任一实施例的基础上，安装腔400的内壁设有锁止结构112，锁止结构112设置于芯体110的外壁上和/或定位套300的内壁上，当管材600被压缩时，锁止结构112与管材600卡紧配合。当定位套300在卡钳700的作用下压缩变形时，带动管材600压缩变形，此时，锁止结构112与管材600的外壁实现卡紧，防止管材600相对安装腔400的内壁发生松动而脱落，同时，可以将锁止结构112设置为相对芯体110倾斜的卡齿710，管材600 变形后塞满相邻卡齿710之间的间隙从而锁紧管材600，避免了因热胀冷缩形成的间隙，保证了密封性，本实施例的卡齿710为三角斜齿，在其他实施例中，还可以为梯形斜齿等形状。该锁止结构112可以分别设置在芯体110的外壁或定位套300的内壁，也可以在芯体110的外壁和定位套300的内壁同时设置以加强密封效果。
如图1至图3所示，可选地，芯体110的外壁设有供密封圈500安装的安装槽111，安装槽111包括第一侧壁，第一侧壁远离连接体120设置，第一侧壁上设有填料槽1111。在进行管件连接装置的组装使用时，先将密封圈500套入芯体110上的安装槽111内，为了保证密封性，可以沿芯体110的长度方向间隔开设多条安装槽111，再将挡圈穿过芯体110至连接体120，使得挡圈上的第三配合部210与连接体120上的第一配合部121实现配合，从而使得挡圈套设于连接体120上，再将定位套300套设于芯体110上直至定位套300端部的第二配合部330与挡圈上的第四配合部220实现卡接配合，当第二配合部330与第四配合部220配合之后，定位套300相对芯体110间隔设置，由定位套300、芯体110及挡圈配合形成了安装腔400。在安装槽111的第一侧壁上设置填料槽1111，当管材600发生压缩变形时，与填料槽1111相应的部分能够陷入填料槽1111内，从而与密封圈500进一步接触，使得密封圈500进一步被压缩产生变形从而填满安装槽111，防止后续使用过程中因密封圈500没有完成充满安装槽111而发生位移，避免了因密封圈500位移产生间隙。在一个实施例中，填料槽1111的深度L1为0.5mm～0.7mm，填料槽1111的宽度L2为0.5mm～1mm，此时，密封圈500能够被压缩至完全充满安装槽111。
需要进行说明的是，密封圈500可以采用例如O型圈等能够实现密封的元件，该密封圈500可以采用弹性材质，从而使得在压缩后能够变形以充满安装槽111，增强密封性。
如图2、图3及图10所示，进一步地，安装槽111还包括第二侧壁，第二侧壁靠近连接体120设置，第二侧壁上设有防滑壁1112，防滑壁1112的径向高度大于密封圈500的径向高度。防滑壁1112的径向高度大于密封圈500的径向高度，当管材600插入安装腔400时，管材600的侧壁与防滑壁1112抵接，使 得管材600的侧壁与密封圈500之间留有间隙，防止在管材600插入过程中与密封圈500发生接触从而使得密封圈500拱起而位移，同时，由于在管材600插入安装腔400后，管材600与密封圈500之间留有间隙，若管件连接装置没有进行卡钳700的咬合，在后续进行打压测试过程中，液体L从间隙中溢出，从而可以判断出管件连接装置还未使用卡钳700进行压接咬合。在一个实施例中，径向高度差L3为0.1mm～0.3mm，此时，不仅可以指示是否进行钳压，还能保证后续进行压缩之后能够实现可靠的密封。
如图2所示，在上述任一实施例的基础上，连接体120上还设有第一导向部122，第一导向部122靠近第一配合部121设置。第一导向部122的设置使得挡圈能够顺畅的位移至使第三配合部210与第一配合部121进行配合。在一个实施例中，第一导向部122为导向斜面，该导向斜面朝向第一配合部121倾斜，即靠近第一配合部121的一端高于远离第一配合部121的一端，挡圈在套入连接体120上时，通孔的内壁先与导向斜面抵接，继续施加朝向连接体120的外力时，空腔的内壁沿导向斜面移动直至第二配合部330与第一配合部121配合，导向斜面还能有效阻挡挡圈脱落。
如图4所示，在上述任一实施例的基础上，定位套300还设有第二导向部340，第二导向部340靠近第二卡接部设置。第二导向部340的设置使得定位套300上的第二配合部330能够顺畅的与挡圈上的第四配合部220实现配合。在一个实施例中，第二导向部340为圆弧过渡的端部，在定位套300朝向挡圈移动至接触的过程中，圆弧过渡的端部能够顺畅的嵌入挡圈内，使得定位套300的端部收缩，从而使得第二配合部330与第四配合部220相配合，实现定位套300的安装固定。
如图4及图10所示，在上述任一实施例的基础上，定位筋310上设有连通安装腔400的窥视孔311。通过窥视孔311可以判断出管材600插入安装腔400内的深度，管材600插入安装腔400内的深度达到预设条件，经过压缩之后才能有效的保证其密封性。可以将窥视孔311设置于靠近挡圈的定位筋310上，从而可判断出管材600是否插入至与挡圈抵接。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对 上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的约束。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
